@vishalrao Will have to check that on other laptop. On current (office) laptop i don't have admin right to change settings.
CHANGE THE MTU VALUE FROM 1492 to 1460. then netflix will work like charm@Ameen , Ive also been having problems with Netflix streaming, mainly since last 2-3 months. Sometimes it drops from 4k to hd. Very seldom to 720p, when it becomes noticeably bad. Testing netflix (using its app's test network option) shows only 30 mbps. It was earlier close to 100. Perhaps you could check this option also.
The same device, using same network is able to steam Amazon prime at 4k.
